File:Dick Tracy and 2-Way Wrist Radio.jpg

Summary
Dick Tracy uses his famous 2-Way Wrist Radio in this panel from a 1952 strip. Note the callout indicating its presence on Tracy's wrist; captions such as these, explicitly pointing out something important to the plot, are a signature and often-parodied element of Chester Gould's cartooning style.

Fair Use Rationale for article Dick Tracy
Given the iconic nature of the device being depicted and its connection to the Dick Tracy comic strip, a single panel showing the character using it appears called for. The panel is scanned at a slightly higher resolution than may be considered normal, but this is only done to ensure readability of the callout.
